I tried the same trick that we used for ALDSP 2.0 -- placing a compatible version of javax.namespace.QName in the lib/endorsed directory of the JVM being used by WebLogic 8.1. That change permitted a standalone Java 1.5 client to execute correctly. However, running the same code in a servlet hosted by WebLogic 9.1 generated this exception:
<Apr 12, 2006 10:55:21 AM MDT>
<Error>
